So, I love that the README is nearly as long as the code itself.
Shorthand:
PATH=$HOME/.bans:$PATH # (prefix path with "banned" cmd-dir)
printf "echo 'bad!'" > "$HOME/bans/some-cmd" # (make `some-cmd` run `echo 'bad!'`)
As to the sibling "why?" ... it's trivial to circumvent: `ban ls "I run it too much..."`, `/bin/ls` is still unaffected, `rm ~/.bans/ls`, etc... but I _do_ like the pause to allow a return to rationality, eg: "Hey, maybe I do run `ls` too much..." and then deciding how to proceed.
It'd probably be nicer if it did something like `(Bad) Chrome.app/*` on OSX, but as an exercise in shell gymnastics, I'm kindof all here for it! :-)

This cant be a though someone has ever had. Your telling me people are getting addicted to the ls command?
I think it's more an example of a "why did I just cd ls cd ls cd ls that directory tree instead of leveraging tab completion" type thing than "man, I gotta get over my ls addiction or I won't be able to provide for my family".
I've found myself doing similar hints to nudge more efficient-but-less-exercised things into my day to day usage. E.g. making /etc/crontab a comment to get more used to creating systemd timers instead. Otherwise I'd just do it without thinking.

Sometimes I find myself repeatedly ls'ing even though I'm making good use of tab completion. There's something about seeing the names that helps with remembering what I was going to do.
This is why I like GUIs. Seeing the files that are modified in my git gui reminds me of what Im doing instead of running git status. And seeing all the available things I could do is more stimulating than having to keep coming up with the text commands to type.
For that I use Git Cola[1], it is quite nice.

Come to think of it, I would probably benefit from rate-limiting myself on `git status`.
I am. Every time I cd I ls even though I know what's in there.
This popped up on HN last week: https://github.com/mieubrisse/cmdk I don't really get it but apparently some people really have issues with ls and cd and feel they use them too much.
Bad habits do happen. I forced myself out of `sudo su` and into `sudo -i` by configuring my sudo rule to allow any command except `su`.
I'm addicted to sl. I love those trains.
